Any good webmaster knows the cardinal rules of website optimization. Yahoo! wrote them all up years ago on its Developer Network site. And the more of these rules you can adhere to, the faster your site will load for your visitors. But, more and more often as sites turn to using asynchronous technologies like AJAX to make their sites more responsive and act more like applications, the old rules lose their effectiveness.

Today, the website wizards behind Digg have revealed a new technology called MXHR, or Multi-Part XML HTTP Requests, as a method for optimizing delivery of Digg's complex AJAX-enhanced site. The implementation of MXHR is an addition to Digg's User Interface Library, called DUI.Stream. While still in a fairly rough early stage, Digg believes that MXHR will eventually give it a huge boost in un-cached page rendering efficiency.
